angularJs利用$scope处理升降序的方法

如下所示：<divng-app="module"ng-controller="ctrl"><tableborder="1"width="600"><tr><tdng-click=

如下所示：

<div ng-app="module" ng-controller="ctrl">
 <table border="1" width="600">
 <tr>
 <td ng-click="orderBy('id')">编号
 <span ng-if="status.id">升序</span>
 <span ng-if="!status.id">降序</span>
 </td>
 <td ng-click="orderBy('click')">点击数
 <span ng-if="status.click">升序</span>
 <span ng-if="!status.click">降序</span>
 </td>
 <td ng-click="orderBy('title')">标题
 <span ng-if="status.title">升序</span>
 <span ng-if="!status.title">降序</span>
 </td>
 </tr>
 <tr ng-repeat="(k,v) in data">
 <td>{{v.id}}</td>
 <td>{{v.click}}</td>
 <td>{{v.title}}</td>
 </tr>
 </table>
</div>
<script>
 var m = angular.module('module', []);
 m.controller('ctrl', ['$scope', '$filter', function ($scope, $filter) {
 $scope.data = [
 {id: 1, click: 100, title: '百度'},
 {id: 2, click: 200, title: '谷歌'},
 {id: 3, click: 300, title: '腾讯'},
 ];
 //记录排序的状态
 $scope.status = {id: false, click: false, title: false};
 $scope.orderBy = function (field) {
 /*切换升序和降序*/
 $scope.status[field]=!$scope.status[field];
 $scope.data = $filter('orderBy')($scope.data, field, $scope.status[field]);
 }
 }]);
</script>
